Why not just drop them and then recreate them?  EM makes it easy to make the 
scripts.

Subject: Table constraints

Hi,

I am trying to create a stored procedure to delete all data from the tables in 
a test database.
So we can fill it with a data set, run tests and load another set of data....

Deleting the data itself is not an issue.  But we have many relationships 
between tables. So just doing a loop over the tables to delete the data gets 
constraint errors.  Its not a big deal to run the SP a few times, but I was 
wondering if there was a way to query for the relations, delete/suspend them 
and then add them back?

So far my SP looks like:


ALTER  PROCEDURE [dbo].[SP_DataDump]

        @Tblname varchar(250)

AS

DECLARE @tableName varchar(250)
DECLARE @newSQL varchar(1000)

IF (@Tblname = 'all')
        BEGIN
                DECLARE tables_csr cursor for
                Select name
                From sysObjects
                Where type = 'U' and Patindex('%_LU_%', name ) = 0 
        END
ELSE
        BEGIN
                DECLARE tables_csr cursor for
                Select name
                From sysObjects
                Where type = 'U' and Patindex('%'[EMAIL PROTECTED] '%', name )
> 0
        END


Open tables_csr
fetch next from tables_csr into @tableName
while @@fetch_status = 0
Begin

        SET @newSQL = 'Delete From ' + @tablename
         
        exec(@newSQL)


        fetch next from tables_csr into @tableName

end


_LU_ are our "LOOKUP" tables like states etc, data never changes so
don't need/want to empty them.


I know a similar statement to this can add/remove the constraints. I
just don't know how/if possible to get the constraints for each table in
the sp.


ALTER TABLE [dbo].[Components_tbl]  WITH CHECK ADD  CONSTRAINT
[FK_Components_tbl_Image_tbl] FOREIGN KEY([ImageID])
REFERENCES [dbo].[Image_tbl] ([ImageID])


Any help would be appreciated.
Rodney
